Patented Jan. 29, 1935 UNITED STATE/s PATENT otrl'ciElv 1,989,297 oLosURE oAP LooK' A c Kyle E. stam, oonnersville, Ind. y Application october 1s, 1932, serial No. ,639,959 s claims. (ci. 22o-24) This invention relates to improvements for closure caps forcontainers such as automobile fuel tanks, radiators or the like. More specifically it relates to closures of the hinged'or lid type in which the base or collar portion thereof must be fastened permanently and securely to the container. 1

The main object of the invention is the provision of a device of the class described which may be easily, quickly and permanently attached to the ller opening of a container without the use of special tools or any great amount of mechanical knowledge, and a means thereon to prevent unauthorized removal of the cap from the ller opening.

Another important object is the provision of such a device in which is contained suitable means as will allow adjustment of the cap axially of the filler opening so as to allow the hinged lid to open in a convenient direction.

These, as well as other objects, will become more apparent upon consideration of the drawing and description specifically related thereto.

Referring to the drawing:

In the present embodiment of the invention, the drawing shows a portion of the ller neck 8, having thereon ianged portions 9 and 10. Depending from the flanges 9 and 10 are the cam and stop members 11 and 12, and cut through the flanges 9 and 10 are the entrance openings 13 and 14. 'I'he collar is designated by the numeral 15 and the cover for the collar is numbered 16. This cover is not a part of this invention as any suitable cover may be used. Located around the inside diameter of collar 15 is a shoulder 17. This shoulder performs a dual purpose; rst, it is adapted to press the gasket 18 against the end of the ller tube 8; and second, it carries upon its upper surface the ring 19. Carried on the shoulder 17 is therivet 20 which ts holes 21, and 23 `*inthe there n being three holes'in the present embodiment which allowk three different positions ofthebase ,and lid rotativelyof the spout. It is obvious that there maybe a greater or lesser number of holes as preferred. Depending from the'ring 19 are the rigid hook members 24 and 25 .which are `adapted to operate'on camsr 11-'11 and stops 12e-12. -These hooks are herein showniand iconsidered as being formed integral with the .ring

19, but need not necessarily be ,constructed in such manner, as they may be formed separately and fastened in any solid and rigidmanner to the ring member. Also, carried on ,the ring 19 and depending therefrom is the resilient or yielding member 26. This member may-be made either of a soft yielding material which maybe bent into the desired position manually, orA it may be made of a spring-like or resilient material which will assume the desired position automatically. Thepperation of the member 26. will be explained more. in .detail hereinafter.

The novel features of this device will be better understood by a description of the operation of installing it on a filler-spout. f f

Installation is accomplished by .placinggth'e hoo-ks 24 and 25 down through the ller spout entrance openings 13 and 14, and turning' the collar,until thehooks nstrike the stops) 12-,12 as is clearly shown in Fig. 4. l When thelcollar is position alongside one of the cams 11. i If, the Vmember 26 isbf a resilient nature, it .will be pressing againstjtheside of the A.cam-,but if itzis made of a yielding or manually bendable material, it simply depends along the side of the cam but does not press thereagainst.

If the member 26 is resilient it will ride against the side of the cam 11 when the collar is turned until it reaches the opening 13 or 14, then, because of its resilient nature, it will spring outward into this opening and therefore back of the stop 12. When the member 26 is in the opening 13 or 14 it prevents reverse rotation of the collar to remove it from the filler spout.

If the member 26 is not resilient but is of a soft or yielding nature, it accomplishes the same purpose. It is rotated by the collar to a position directly in front of the opening 13 or 14 and is then bent manually into the opening and back of the stop 12. In both the case of the resilient member 26 and the soft or yielding member 26, the said member is located on the ring in a predetermined, spaced relationship to the hooks 24 and so that it may pass entirely into the opening 13 or 14 before the hooks strike the stops 12.

Removal of the device from the filler spout is accomplished by simply grasping the key niember by its lower end or prying thereon with a suitable tool so that the said key member is moved out of the entrance opening, then rotating the collar anti-clockwise until the hooks may be lifted up through the entrance openings of the spout.

The .gasket I8 maybe of anysuitable material which is of a compressible or resilient nature.

Cork or rubber are the most common materials' which could be used for this purpose. The hooks 24 and 25 are of such shape 4and are lso spaced from the shoulder 1'7 on the collanfthat when the collar is rotated on the filler spout, they coact with the cams on 'the `spout to compress the gasket 18 between the ller spout `and the shoulder 17, thus sealing the collar to the spout.
